SETTINGS & MONITORS TAB
The
Settings & Monitors
tab is used as the main control for
remote operation.
Power:
The
Power
button functions the same as the front
panel power switch on the instrument.
Enable
: The
Enable
button enables current to the load and
functions the same as the Enable button on the front panel of
the QCL LAB instrument.
SETTINGS
Setpoint (A):
In the
Setpoint
control, type the desired
setpoint, in Amps, that will be driven to the load. The range
is 0 Amps to the maximum output current allowed by the QCL
LAB instrument selected.
Current Limit (A):
In the
Current Limit
control, type the
maximum value, in Amps, that the QCL LAB instrument
should not exceed to the laser. The range must be between
8% and 120% of the maximum current allowed by the QCL
LAB instrument selected.
Max Supply Voltage (V):
In the
Max Supply Voltage
control,
type the maximum voltage, in Volts, from the internal supply.
The range must be between 18 V and 28 V. The available
voltage to the load is about 8 V below the value specified.
Cable Resistance (Ω):
In the
Cable Resistance
control, type
the resistance of the cable, in Ohms, between the QCL LAB
instrument and the load. The QCL voltage displayed will be:
V
DISPLAYED
= V
ACTUAL
- (R
CABLE
* I
OUTPUT
)
This calibration parameter gives a better representation of the
voltage at the actual load. The range is 0 to 4 Ohms.
Turn On Delay (msec):
In the
Turn On Delay
control, type
the time, in milliseconds, to delay sending current to the load
after the
Enable
button or control is pressed. The range is an
integer between 1 and 25500 milliseconds. Factory default is
2 seconds to match CDRH safety requirements.
MONITORS
Actual QCL Current (A):
Monitor output current, in Amps, to
the load.
Actual QCL Voltage (V):
Monitor output voltage, in Volts, to
the load.
Interlock Status:
The green indicator illuminates when all
interlocks are set to enable the output current. The front panel
key switch must be turned to ON (unlocked), and active and
passive interlock inputs on the rear panel must be configured
to allow output. When this indicator is grayed and the Enable
button is pushed, an interlock error will be triggered by the
QCL LAB instrument.
